Engine Cooling System: Maintenance Lincoln MKS I

Filling and Bleeding without RADIATOR REFILLER

Note. Engine coolant provides freeze protection, boil protection, cooling efficiency and corrosion protection to the engine and cooling components. In order to obtain these protections, the engine coolant must be maintained at the correct concentration and fluid level. To maintain the integrity of the coolant and the cooling system: NOTE: Genuine Mazda® Extended Life Coolant and Motorcraft® Specialty Green Engine Coolant are very sensitive to light. Do NOT allow these products to be exposed to ANY LIGHT for more than a day or two. Extended light exposure causes these products to degrade. Add Motorcraft® Specialty Green Engine Coolant to the cooling system. Do not add alcohol, methanol or brine, or any engine coolants mixed with alcohol or methanol antifreeze. These can cause engine damage from overheating or freezing. Ford Motor Company does NOT recommend the use of recycled engine coolant in vehicles.

Note. Stop-leak style pellets/products must not be used as an additive in this engine cooling system. The addition of stop-leak style pellets/products may clog or damage the cooling system, resulting in degraded cooling system performance and/or failure.

1. Open the degas bottle cap and fill the degas bottle to 25 mm (0.984 in) above the top of the COLD FILL RANGE. Recommended coolant concentration is 50/50 ethylene glycol to distilled water. Maximum coolant concentration is 60/40 for cold weather areas. Minimum coolant concentration is 40/60 for warm weather areas.
2. Close the degas bottle cap.
3. Turn the HVAC system to OFF.
4. Run the engine at 3,500 rpm for 30 seconds.
5. Turn the engine off for 1 minute to purge any large air pockets.
6. Start the engine and let idle until the engine reaches normal operating temperature and the thermostat is fully open. A fully open thermostat can be verified by the radiator fan cycling on at least once.
7. Run the engine at 3,500 rpm for 30 seconds.
8. Run the engine at idle for 30 seconds.
9. Turn the engine off for 1 minute.
10. Repeat Steps 7 through 9 a total of 10 times to remove any remaining air trapped in the system.
11. Check the engine coolant level in the degas bottle and fill to 25 mm (0.984 in) above the top of the COLD FILL RANGE when warm or to the top of the COLD FILL RANGE line when cold.
12. Install the degas bottle cap to at least one audible "click."
